WALL-BRACKET.

Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed May 21, 1914. Serial No. 840,022.

To all whom it may concern:

- a citizen of the United States, and a resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Wall- Brackets, of which the following is a specification.

The object of this invention is to provide means whereby a wall bracket may be adjusted after its socket pieces have'been secured to the Wall so as to bring the bracket into a true vertical position.

A further object is to provide certain other features in a pivoted adjustable wall bracket whereby the same may be adjusted very easily and accurately to the desired po- 7 sition.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 represents the bracket in top plan, the sliding parallel bars being shown in full lines in one position and in dotted lines in another position, Fig. 2 represents a view in side elevation partly in section of the bracket, the parts being shown in one position in full lines and in two'other positions in dotted lines, Fig. 3 is a front view of the upper fiXed wall socket, Fig. 4 is a transverse section taken in the plane of the line AA of Fig. 3, Fig. 5 is a vertical section taken in the plane of the line BB of Fig. 3, F ig. 6 is a detail view showing the bearings for one of the parallel bars of the bracket, and Fig. 7 is a detail section taken in the planeof the line G-O of Fig. 1.

The spider to which the table is. secured is denoted by 1, which spider is provided with a pivot 2 rotatable in a cross piece 3 which spaces the outer ends of two horizontally'arranged parallel bars 4, 5, slidable in the head 6 of the outer member 7 of the bracket arm. This outer member 7 is pivoted at 8 to the outer end of the intermediate member 9 of the bracket arm, the inner end of which member is pivoted at 10 to the inner member 11 of the said arm. The inner member 11 has top and bottom convexsided hinge pintles 12, which are inserted in straight-sided bores 13 of bearings 14 located in recesses 15 of top and bottom socket pieces 16 fixed to the wall or other vertical support by fastening means such,

for instance. as screws 17.

Each bearing 14 may be adjusted laterally outwardly and inwardly in its recess 15 so as to bring the bracket arm into a true vertical position so that the bracket arm will stay in any of its adjusted posi tions when swung to such positions on the hinge pintles 12. Each of these bearings 14: has a sliding interlocked engagement with and is laterally adjusted by a screw 18 rotatably mounted in the socket piece. This screw is held against removal, as, for instance, by a pin 19 entering a circumferentlal recess 20 in said screw.

A traveling nut 21 on the screw is provided with flattened surfaces engaging the upper and lower walls of a slot 22 in the bearing, said traveling not having flanges 23 arranged-to engage the bearing to move it laterally in either direction according to the direction which the screw 18 is turned. Each of these bearings is adjusted outwardly and inwardly by an adjusting screw 24 screw threaded in the socket piece 16. The bearing 14 has an interlocked sliding engagement with the screw 24 through a sliding block 25 carried by the inner end of the screw whereby the bearing may be moved laterally on the head and yet will be moved outwardly or inwardly along the recess 15 by the turning of the screw in one or the other direction. The outer end of the screw may have a kerf 26 and both ends of the screw 18 may have kerfs '27 for insertion of a tool for turning them. By these adjustments, the bracket arm may be accurately adjusted into the desired position to swing properly irrespective of the wall or other support to which it is attached.

The intermediate member 9 of the bracket arm may be adjusted vertically to difierent positions and held in such adjustments by providing the inner member 11 with a ratchet 28 and the intermediate member 9 with a pawl 29 arranged to engage said ratchet. This pawl is provided with a stem 30 slidably mounted in the intermediate member 9. A spring 31 serves to hold the pawl in engagement with the ratchet 28. The pawl may be drawn outwardly out oi engagement with the ratchet by means of a handle 32 slidable along the under side of the intermediate member 9 of the arm and secured at 33 to the outer end of the stem of the pawl. This handle has a finger piece 361 for facilitating its operation.

The outer member 7 of the bracket arm is maintained in its vertical position irrespective of the adjustment of the intermediate member 9 by providing a connecting rod comprising inner, outer and intermediate sections 35, 36, 37. The inner and outer ends of this connecting rod are pivoted to the inner and outer members of the bracket arm 5 at equal distances fromthe pivotal connections 10 and S. The intermediate section 37 of this connecting rod is rotatably engaged at 38 with the outer section 36 and has a screw threaded engagement, as shown at 39, with the inner section so that by turning the intermediate section 37 the outer member 7 of the bracket arm may be accurately adjusted to its vertical position. To insure the easy sliding of the parallel bars 1, 5, in the head, the bore for each bar is preferably made larger than the bar and end bearings 10 are provided which snugly fit the bar and are held in position by screw caps ll. These bearings may be readily replaced when worn.

WVhile I have shown and described my invention in connection with a dental wall bracket, it is to be understood that I do not wish to limit myself to this particular type of wall bracket but contemplate the use of my improvement in wall brackets of all types wherever applicable.
